When you pound out fast octaves or chords (Liszt, Chopin), do you use your arms? wrists? both?I bet that if I learned, I could play octaves pretty quickly with my wrists doing all of the verticle motion, but I don't know which way to go.Another question, how relaxed should I be when I play? I do have some tension and my back always aches when I finish playing. The only tension I feel, however, is in my arms and sometimes jaw.
Stepping in for Xvimbi, here....
yes. the alexander technique does make playing more relaxing! you aren't striving to "break through" so much as completely relax when you are playing a very difficult passage (for me octaves and large chords). i no longer 'lock into position' but maintain a general hand arch within a flatter hand (hand has eliptical arch toward your arm instead of rainbow arch going up - as i used to teach) when you use less hand arch up, you need less wrist action, less arm action ... and you can play more by touching (feeling) pinky taking each consecutive octave or chord. i hope this is right. it seems to be the way i have observed and understand my teacher to play.
What about the octaves near the beginning of the Mephisto Waltz?With the 4th leaps consecutively?How should i practice these?
On backaches etc. When you sit at the piano you should always with your legs not ass, just under your backside and at the edge of the seat.
